REVERSING' 'VALVE FOR REGENERATIVE FURNACES.

Application 'filed October 4, 1919, Serial No. 328,521. Renewed February 16, 1922. Serial No. 537,124.

To all 'whom t may concer/n: f. I

the following is aispecication.

My present invention consists in an improved valve 01 damper system of particular utility in controlling flow through air and gas conduits of relatively large size, and especially devised for controlling the supply of air under pressure to, and escape of products of combustion from, the regenerators of a regenerative coke oven battery.

The general object of the invention is to provide simple and effective apparatus for the purpose specilied which will be relatively inexpensive Aand durable, and easy to manlpulate and to maintain in efficient condition. `More specifically my invention has for its object an improved construction and arrangement of the air supply andwaste product conduits and reversing valves which are ordinarily located at the end of a re-- generative coke oven, and which form the means for intermittently and alternately connecting` a draft creating device such as a stack and air compressor or other source of air under pressure to distributing conduits running longitudinally of the battery and connectedV Vto the various regenerators.

-The various features. of novelty which characterize my invention are pointed out with particularity in the claims annexed to `and forming la part of this specication. For a better understanding of the invention, however, and the advantages and speciic Objects attained with its use, reference should be had to the accompanying drawings and descriptive matter in which I have illustrated and described a preferred embodiment of my invention.

Cf the drawings:

Fig. lis a sectional elevation of a portion of a coke oven` battery, the'section being taken on the line 1-1 of Fig. 2.

I Fig. 2 is a plan partly in section on the l1ne2-2 of Fig. 1.

Fig. 3 is a partial section on the line 3 3 of Flg. l; and

Fig. 4 is a partial section on the line 4-4 of Fig. 1.

In the drawings I have illustrated -only so much of a coke oven structure proper as is essential to an understanding ofl my present invention.

In the construction illustrated there is provided at one end of the coke oven battery B a transversely extending off take or waste products conduit C, and a transversely extending air supply conduit E. The conduit C is provided with an outlet C between its ends which runs to a stack or other draft suction creating device not shown. Air under pressure is supplied to the conduit D between the ends of the latter through a supply connection E connected to the outlet of a fan or blower E. Reversing valves or dampers F and F form means for opening and closing communication between the ends of the conduits C and D and distributing conduits running longitudinally of the battery and connected to the regenerators (not shown) thereof. As shown the coke oven batter comprises but two of these distributing c annels A and A located one each side of the battery and each connected alternately to the adjacent ends of the ,two transverse conduits C and D. When the conduit A at the one side of the battery is in communication with the' trans- Verse conduit C, for example, vit serves as a means for passing products of combustion from the regenerators at the one side.

of the battery into the conduit C and thencei to the stack, andv when the conduit A is connected to the conduit D it serves as a means to distribute compressed airsupplied by the fan or blower E to the regenerator to which the conduit A is connected. The

conduit A is connected to the cross conduits C and D respectively, during the periods in In some instances, as in the construction shown, the conduits C and D are both conveniently formed of masonry, though these conduits, and particularly the conduit D, ma well be made of metal. The conduit D 1s located directly above-the conduit C which, as shown, lies between approximately the same levels as the passages A and A. A port DA which is vshown as formed-partly site end of the conduit D to the passage A Communication between the passages A and A the outlet C from the conduit C and the inlet D to the conduit D is controlled by a valve or damper F in the form of a plate-like body normally made'of cast iron which is slidingly mounted in a guidep way Cr slightly incllned to the vertical and located between the inlet D. and outlet C on the one hand and the port DA and passage A on the other hand. As shown, the guidewa G is located directly adjacent the port D and extends across the conduits C and D. Communication between the opposite ends of the conduits C and D and the conduit is controlled by a valve F similar to the valve F and Working in a guideway Gr `similar to the guideway Gr. The valves F and F are connected by chains or cables H and H respectively to the usual reversing mechanism I.

The ports are so constructed that in one condition of operation, as shown, the valve F is lowered and closes communication between the passage A and conduit C, while leaving the passage A and conduit D in open communication, while at the same time the valve F is raised and closes communication between the conduit D and passage A', while leavin communication open between conduit. and passage A. half revolution of the crank arm I of the reversing mechanism the valve F is raised to open communication between conduit C and passage A and close communicationbetween passage A and conduit D; while the valve F is then lowered closing communication between conduit C and passage' A and leaving opencommunication between conduit D and passage A.

The guidevvays G and G may each be formed, as shown best in Fig. 4.-, of a pair of channel bar members embedded in the masonry at the opposite sides of the conduits C and D.

The por-tion of the valve member proper entering each channel is of a thickness less y than the distance between the ribs of the channel bar and is gravity held against one rib only which thus forms the side of the seat for the valve. The contracting surl nasceva i faces of the valve body and its guidewa may advantageously be machined. Metal,- lic boxes g are shown as receivingthe u'- per ends of the valves when in their e vated positions. These boxes are closed at theirA upper ends except for the necessa passesV for the valveohains or cables and thereb prevent leakage out of the conduit D a ong the valve vguide- The construction shown is characterized by its extreme simplicity and by' its certainty of operation.- rlhe valves F and F each of whlch weigh a ton or so, are held by gravity a ainst their seats in either position with s cient force to give tightjoints, while at the same time the frictional resistance to the movement-of the "heavy valves is not excessive.

When necessary for inspection, cleaning or repairs, access may be had to the valves and valve guideways by opening the doors d rovided -ior the urpose at the opposite en s of the conduit 4 While in accordance with the provisions of the statutes l have illustrated and described the best embodiment of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of apparatus disclosed without departing from4 the spirit of my invention as setl forth in the appended claims, and that under some conditions certain features of my invention maybe used to advantage without a corresponding use of other features.

Having now what I claim as new and desire to secure by Letters Patent, is:

1. ln a regenerative coke oven having distributing channels extending longitudinally of the oven batery and connected to the regenerators thereof, the improved means for supplying air under pressure, and for withdrawing products of combustion from said distributing channels which comprise a pair of conduits extending transversely oit' the oven structure and ardescribed my invention,

ranged' one above the other, a pair of reversing valves spaced apart longitudinally of said conduits and each movable from one position in which it closes one of said conduits to a second position in which it closes the other of said conduits, means for supplying air under pressure'to one of said conduits between said valves, and a products of combustion outlet opening from the other conduit between said valves.

2. In a regenerative furnace the combination with a pair of passages serving alternately as supply and exhaust passages of two conduits arranged one above the other and each connected at one end to one of the said passages and at the other end to the other of said passges and connected 10 duits. at thesame time and a reversing mechanism for raising and lowering one of sand valves and slmultaineously lowering and raising the other of said valves.

Signed at New York, in the county of New York and Stateof New York, this 15 third day of October D. 1919.
